My invention relates to toilets.

It has among its objects to provide an improved flushing means for a toilet. A further object of my invention is to provide improved means adapted to provide a prolonged flow of flushing water while being adapted to use with an ordinary small diameter supply .pipe and with an ordinary type of diaphragm operated flush vvalve and while also eliminating the need for other controlling mechanism .and for the large tanks heretofore necessary. A still further object of any invention ,isto provide such improved means includingan improved connection and arrangement of a plurality of tanks, whereby it is made possible to utilize air pressure in one of thetanks and thereafter gravityflow from said tanks, in such manner as thereby substantially to prolong the flow available for flushing while operating entirely under the control of the flush valve Still other objects of my invention are .to provide such an improved .means which is especially adapted to .use in connection with a toilet of the combined urinal and squat :type described and-claimed in my copendingapplication Serial ,No. 235,010, and wherein my improved tanks are adapted to v be disposed inan improved .manner in the urinal member of such a toilet while supplying water for ,fiushing thesquattype toilet at the .base thereof and being controlled by the flush .valveadjacent this base. These and other objects and advantages of my improved construction will, however, hereinafter morefully appear.

In, the accompanying drawing, I have shown for purposes of illustration one embodiment which my invention may assume in practice, the same, although not limited to use in connection therewith, being illustrated in connection with a toilet of the construction shown in my application mentioned.

In the drawing:

Figure 1 is a perspective view of such a toilet equipped with my improvements, certain portime being broken away and others shown in dotted lines to facilitate illustration, and

'2 is a simplified view of the flushing structure removed from the toilet, this structure beshown in somewhat diagrammatic form and partially in'section, to facilitate illustration.

iis illustrative construction, the toilet is of cated at i and hereinafter more fully described, being disposed within this member 3 and controlled by a usual flush valve .5 having a diaphragmlla and operating handle 5b and disposed adjacent the base ,i at one side thereof, which ,FQSJVGEEQOHTJIOIS the flow of flushing water from \a water line .6 through .my improved means l to flushing outlets l disposed around the upper edge of the bowl 2. v

Referring more particularly to my improved structure, it will beobserved that in rear of the vertically groovedurinal surface 3 on the member 3,-the latter memberis hollow'or chambered, as-shown-at 9, to provide ample space to receivelthe flushing mechanism l, while permitting the member -3-to retain its customary general conformation. Further,-due to the curved or grooved .front face 8thereon, it will be observed that the-chamber!) is of greater depth at its oppositesidesthan it is along its vertical center line, and that I have utilized this fact to enable me todispose my improved flushing mechanisrnin an improved compact arrangement within the member Band thereby eliminate the necessity for anyoutside tanks.

Referring more particularly to the mechanism l, it will .be observed that the same includes tanks Ill and H, herein disposed vertically in these portions-of increased depth along opposite vertical sides and within the member 3. preferred construction, these tanks are of a rel- .ativelysmalldiameter, in such manner as to enable them to be received within these spaces without requiring any undue depth of or change in the member 3. As shown, the left-hand tank 4 connected atits'top to the water supply line in an :usual manner at a point within, the member 3, and herein just beyond a flush pipe whichleads to a urinal'flushing connection l3 at the top of the member 3. The other tank ii .is disposed parallel to the tank It! and in the other enlargement of the member 3. Both tanks hereirnas preferably, are also of the same diand length. If desired, they may be connected together at their top-by a suitable transdiameter .as the pipe !5, to the flush valve 5,

while the latter is connected to the flush connection l by a pipe ll, preferably of the same Ina til

diameter as the pipes 55 and I6. Thus it will be observed that while the inlet pipe 6 remains of usual small diameter, the pipes l5 and H on opposite sides of the diaphragm 5a of the valve 5 are of equal diameter and both of larger diameter than the pipe In the use of this construction, it will be evident that when the valve 5 is closed, air will be trapped in the top of the tank 5 in the space indicated at E8 and be under such pressure as is in the pipe 6, while the remainder of both tanks will be filled with water from this pipe 6. Consequently, when the valve 5 is opened, as, for example, by raising or lowering its operating handle 5b, a flow of flushing water will be established and maintained when the valve diaphragm 5a is opened, from both tanks lil and ll through the pipe Hi to the valve 5 and through the latter and the pipe I! to the flushing connection 1. Further, the water in the tank l I will continue to be acted upon by the pressure built up in the top thereof until, as this tank is emptied, this pressure can no longer function, whereupon there will be a gravity flow from both tanks until both have emptied as much as is possible due to the continued flow into the tank I through pipe 6. When, however, the valve closes automatically, in the manner usual with such valves, the tanks will again fill, as shown in Figure 2.

As a result of my improved construction it is possible to obtain a now of flushing water substantially in excess of that which would be delivered directly from a pipe 6 to a flush valve 5 and the outlet 7, while maintaining the piping, including the pipe 6, of usual and inexpensive small diameter and the valve 5 open longer than has heretofore been possible. Also, it is made possible to obtain such a large flow while requiring only a small tank which can be conveniently disposed in locations not now possible, as, for example, within a urinal as herein or between the studding of a building wall. In my improved construction, the additional water in the tank I! is available and it is also made possible to utilize the pressure of the air in the top l8 of this tank, in such manner as very effectively to prolong the flushing effect, as compared with previous constructions of which I am advised. Further, whereas it has heretofore been impractical without a large tank to use such a valve with a pipe which leads therefrom to the flushing outlets, as, for example, the pipe II, which is of larger diameter than the inlet pipe 6, in my improved construction, this difficulty has been overcome without requiring such a tank. Further, it will be observed that my improved construction makes unnecessary the use of any float or any other control mechanism, in addition to the valve while the tanks act to increase the flow and pressure to the latter valve in such manner as to enable thesameto fiush and then shut ofi satisfactorily, this being due to the prolonged pressure available to hold the valve 5 open for the necessary longer time.

While I have in this application specifically described one embodiment which my invention may assume in practice, it will be understood that this form of the same is shown for illustrative purposes and that the same may be modified and embodied in various other forms without departing from its spirit or the scope of the appended aims.
